Abstract
A speech synthesis method comprises selecting a predetermined formant parameters from formant parameters according to a pitch pattern, phoneme duration, and phoneme symbol string, generating a plurality of sine waves based on formant frequency and formant phase of the formant parameters selected, multiplying the sine waves by windowing functions of the selected formant parameters, respectively, to generate a plurality of formant waveforms, adding the formant waveforms to generate a plurality of pitch waveforms, and superposing the pitch waveforms according to a pitch period to generate a speech signal.
